You think that one was "mature", check this......
1975 British Leyland Triumph Spitfire. I was in the Air Force and this bright yellow ride cost me $5700.00 for a $7200.00 car if bought stateside.
The English backroads were my race track. Officer/pilots used to bring their 'vettes over for their tour and it was immense fun to spank them in road races.
At that time the Spitfire was the highest cornering G-Force car you could buy. I wonder if that's still true.
My old "mature" ass can still remember the British license
plate # MOK362P ,Ah....the memories!
