Hello G1EN,
i've owned an Escort Cossie & driven a Z4M for a few days. The Z4M is a nice car, looks great, fast but I would'nt sell an Escort Cossie for one. I found the interior quite cheap, Everyone I spoke to said the same, alot of money for a BMW with only 2 seats (£45K for the one I drove), I would go for an M3
Cheers
Kevbo
