We’re going to go on record to say that Triumph TR7s will likely never skyrocket in value.  The combination of British Leyland sub-par build quality, Lucas electrics, and an emissions-choked, underpowered inline-four have all conspired over the years to keep these cars valued well below ten large.  Consequently, we don’t blame enthusiasts for improving the performance of what remains a great-looing, wedge-shaped design.

The seller (and we believe builder) of this 1980 Triumph TR7 currently listed here on Craigslist in Piedmont, South Carolina (Greenville) seems to agree with us. They’ve managed to stuff a GM 3.4 Liter V6 mated to a Tremec T5 five-speed manual under the low bonnet of the TR7.  That, combined with an updated interior and metallic blue repaint, makes this TR7 a more potent example than when it left the Triumph factory.

Currently offered for $10,950, Classic.com, the analytics and search engine for the collector car market, confirms the ask is in line with the five-year rolling average of this guide’s summary for Triumph TR7 roadsters produced between 1978 and 1980.  By clicking on the green dots in the graph below, you can navigate to each comparable car sold as a way to help you evaluate the price of the TR7 featured here:

As a second data point, the  Collector Car Market Review Online Tool reveals the seller’s ask falls between this guide’s #3 “Good” estimate of $6,850 and its #2 “Very Good” appraisal of $11,200.

The shape of things to come.  That was Triumph’s tagline of its new TR7 as it pulled into a triangular garage in TV commercials for the wedge-shaped sports car.  Equipped with coil springs and disc brakes at all four corners, car enthusiasts considered the TR7 the first modern British sports car.  Ironically, Triumph elected to replace the TR6’s complicated independent rear suspension with a more conventional solid axle, a four-link setup that handled very well. From its launch in 1975 through 1978, the TR7 was only available as a coupe out due to the belief the U.S. Federal government would implement rollover standards that never materialized.   Unfortunately, the early TR7s built-in Speke near Liverpool earned a bad reputation as unreliable lemons due to self-destructive tactics deployed by British labor unions before production transferred to Solihull two years later.

The TWS Motors YouTube Channel features this 1980 Triumph TR7 commercial quoting positive reviews from several car magazines of the period:

The extensive undercarriage pictures combined with the other photographs indicate this 1980 Triumph TR7 roadster is a nicely modified and highly detailed example.  With its small fuel tank, you’ll either need to figure out how to get the gas tank sending unit to work with the gas gauge or be very diligent about watching the miles traveled to ensure you don’t run out during a drive.

If you are serious about buying this Triumph restomod, you can start the conversation by emailing the seller.  When you connect, please remember to mention you saw their restored pickup featured here on GuysWithRides.com. Good luck with the purchase!

Here’s the seller’s description:

“1980 Triumph TR7 “V6”

This is an amazing example of a modified Triumph TR7. Great for British car club drives, cars and coffee or just running out for ice cream!

Excellent condition, NO rust.

Custom paint, a brilliant metallic blue with silver metalflake stripes (and red pinstripes) and rocker panels/rear panel painted with Mystique color changing paint. Some very minor paint flaws and scratches.

The stock powertrain was removed and replaced with a 3.4L V6 and T5 five speed manual transmission from a 1994 Chevrolet Camaro. The gauge cluster is also from that car. Exhaust is a custom dual Magnaflow setup. This engine stock has more power than the Rover V8 that was fitted to the TR8 model. The transplant is very cleanly done and looks factory. Sounds fantastic.

The wheels are from an MG ZR/Rover 25/45 over 4 x 100 adapters.

Custom interior with upgraded seats, Nardi wood rimmed steering wheel, new JVC stereo unit with Bluetooth, USB, phone, etc. Four speakers. Tinted side windows.

New parts in the past year:

Front brake rotors and EBC Yellow pads
Rear shoes, slave cylinders and hardware
New Lucas wiper and turn signal switches
Battery
Rear suspension bushings
Fuel pump, tank cleaned out, wiring.

All fluids are fresh

problem areas:

speedo is inaccurate (needs to be programmed)

Car is located near Greenville, SC
