Nice one, dude. Great looking car you got yourself there.
As you say, the Mustang doesn't have leaf springs, but does have the live rear axle which is what people in this country criticise it for on bumpy roads. However, as I found out when I moved from Supra to Corvette, there's a whole lot more to enjoy about a car than just speed and handling. Driving around in that Mustang on a warm summer evening with the top down listening to that exhaust note will put a BIG smile on your face. And you probably won't be passing someone else driving the same car very often!
I always laugh at the comments such as 'prehistoric leaf springs'! The Corvette is the one with leaf springs, but if people would actually bother to research these and not blindly believe the rubbish spouted by Clarkeson, they'd see that it's not got longitudinally mounted strips of metal at each corner, but one composite, transverse mounted leaf spring at each end with dual wishbone suspension at each corner. It's good enough for the Z06 to go round the Top Gear track in some pretty impressive company, so maybe not as 'prehistoric' as some would have you believe.
It's idiot comments like this that you'll have to get used to when owning an American car, but TBH, I wouldn't get rid of my 'vette now for anything that'd cost me this side of about £50k. If someone starts with the whole 'leafsprings/doesn't handle well' cr@p, I just say 'Yeah you're right, it's a rubbish car - don't buy one!' Hopefully it'll stay rare that way.
Enjoy it - it looks fantastic!
