Breathable ‘B: 1973 MG MGB MkIII Roadster- SOLD!

Feb 2021 | Classifinds, Sports Car Saturday

March 19, 2021 Update – we confirmed the seller of this MG “Classifind” deleted their listing, so we’re now able to call this one “SOLD!” While this one got away, please reach out either by email or call Rudy directly if you’d like to be informed when we come across something similar.

The license plate on this 1973 MG MGB we came in March 2021 on Craigslist in Greenwich, Connecticut aptly says why someone should drive a vintage analog sports car: so they can breathe! We love the photography of this seller’s listing, especially the feature picture of the bright red ‘B juxtaposed against a parking lot filled with bland look-like SUVs currently crowding our nation’s roads.  Currently offered at Comparing that price against the Hagerty Insurance Online Valuation Tool confirms the private seller has their MGB priced between this guide’s #3 “Good” estimate of $8,800 and its #2 “Excellent” appraisal of $16,600.  Interestingly, the  Collector Car Market Review Online Tool reveals the ask falls between this guide’s #2 “Very Good” estimate of $11,500 and its #1 “Excellent” appraisal of $19,000.

Here’s Hagerty Insurance’s overview of the ’73 MGB:

“Perhaps responding to purists’ complaints, particularly in the U.S., the 1973 MGB regained a traditional flush grille, though now it was plastic with a cross-hatched design and a central shield badge. The recessed grille with its chrome surround, inner rings, and floating octagon MG badge was discontinued. Wipers were now matte black instead of chrome and a tonneau was standard equipment.

The other big news for the 1973 MGB was the fitment of the alloy Buick-Rover 3.5-liter V8 engine into the GT. The lightweight V8 weighed little more than the MGB’s 4-cylinder and significantly less than the MGC’s 600-plus pound six-cylinder unit. Ken Costello had been fitting V8s into MGBs in the UK since 1970 and the factory improved on his installation, re-routing the manifolds so that the standard hood could be used. Even with the compression ratio reduced to 8.25:1, the performance was sparkling with 0-60 in around eight seconds and a top speed of 125 mph.

Nine LHD GT V8s (some sources say seven) were sent to the U.S., which seemed like the obvious market. However, U.S. emissions were increasingly strict and the Arab oil embargo took place, so the outlook was unfavorable. In addition, British Leyland was miserly in allotting the V8 engines to MG, so total production amounted to a mere 2591 units between 1972-1977. Only 1856 chrome bumper GTs were built, followed by 735 rubber bumper cars.

MGB sales continued at the previous year’s pace, with 21,801 1973 roadsters sold worldwide, 17,403 of which came to the U.S. Only 3178 convertibles were sold in the UK. In addition, 820 RHD and LHD cars were exported elsewhere. A total of 11,550 1973 MGB GTs found buyers, and again unusually, the UK took the majority with 6563 against 3747 coming to the U.S.”

Hagerty also produced this Buyer’s Guide about what to look for when purchasing an MGB:


This is a great-looking sports car that will likely get you compliments and more awards every time you enter it in a classic British car show.

Here’s the seller’s excellent description:

“This is it, this is the vintage car you have been looking for because you know you want to own a piece of British automotive history. I bought this car 4 years ago and put a lot of money into it in parts ($11,000) and it simply drives and looks amazing….lots of compliments) 4 speed transmission, the mechanics on this are solid….cruises at 70mph easily and still pulls when you gas it even more. This little beauty has been so good to me. Odometer reads about 21,000 but the actual mileage is about 111,000 as of today. I am at the 3rd owner of the car and the previous owner gave me all his receipts. He changed the odometer at 90,410 as the odometer stopped working and I have the receipt for that work. Much of what you see on the car was done by me with too much to list but….new convertible top, new rims, all mirrors, bulbs, clutch and clutch masters, Retro sound system with amp (bluetooth, etc), steering wheel, luggage rack, top boot, cockpit cover (not shown), matts, change of seat/interior color, custom visors, seat belts, custom wind screen, threshold plates, mud flaps, trunk carpets, drilled aluminum window handles, Monza exhaust and plenty of engine/mechanical work….have all receipts. Did a tune up in the fall 2019 with a performance coil/wires, etc and the car just runs beautifully. Just put in a new alternator and battery in early 2020. Brand new brakes, rotors and calipers in Nov 2020 just before storage. All gauges work. Body only specs of rust and floor boards have no rust and paint is mostly good but you will certainly see imperfections. This car is not a project…it is ready to drive!! Please, only serious buyers. Feel free to call. Max
