In the most bang for the buck there is almost nothing out there to compete with a DeTomaso Pantera. You can pick one up with 300-400 hp for around $25-30K. The Group 4, GTS, GT5 and GT5S cars all look phenomenal. You can get the thing worked on without breaking the bank. Upgrading the engine to 500, 600 or more HP is easy with all the parts available at your local Ford dealer and performance shops. At Pocono they beat everything ( 308's, 328's, 348's 355's, Jalpa's, Miura's Countach's, Diablo's, Murcielgo's) except Enzo's, F50's F40's, which of course are what 20-30 times the price. Pretty embarassing for the money crowd, eh!?
