Also remember, that the 3rd gens that you drove were probably 10 years older than the 4th gens. Bushings, shocks, springs and body structure all get tired with age.
I am talking stock and my 4th gen road race car is still a PIG. Interesting enough, I was offered a 3rd gen road race car today for next-to-nothing but I have to go to St. Louis to pick up. I am seriously considering it…
