Which year was you looking at overall the Supra has always been a good car through its gens.
Power wise again goes with its gens the MK4 version for instance is a nice car a drivers car with the dash aimed like flying inside a cockpit,but a real shame lacks rear passenger room as we found out many years ago when we went to buy one.
Performance is good on the na version and the TT version with the 2jz engine,the TT version is a bullet proof super tunable engine and was made to compete against the Nissan GT-R which also has a strong engine,power as with the GTR from the TT version is around 500-600bhp with stock internals.the na engine can again be modded to nice power gains.Looks the MK4 still looks great and a head turner.
The mk3 is a great car a bigger car and offers again ice power figures from its engines with a mix of engines the 2jz engine is a nice turbo engine and again used in many engine conversions for drifters etc.With a car which was before its time when came out with technology,and still looks good for its age.
