Well when I was buying mine I wanted the E46 M3 as my dads (above) was one of my fav cars we had. But I had just turned 23 when I bought the Z4Mc and I had about 3 months earlier nearly pulled the trigger on an E46 but the cheapest insurance quote for the E46 M3 was £2600
guessing because so many were made and so many young idiots had bought them and written them off (were not all the same), whereas the Z4M coupe was £1060... No contest really suppose with only 550 in the UK and with about 520 left on the road the write off statistic was a lot lower.
Dont know if you have driven an e46 but the ride is sublime compared to the Z lol which I really liked! I just really wanted and M really and especially the S54 with that raspy exhaust, always loved the Z4Mc but wanted the 4 seats. But one came into my local dealer and as soon as I saw it I was sold quick test drive and signed there and then. So Bought the Z4Mc and bought the cooper S as a run around as I got a spanking deal with it and the part x on my old cooper. Was a fun week picked up the brand new Cs and a week later the Z4Mc.
In a perfect world I would run a 2 seater like the Z4M as a weekend car and have an M3 as a daily/family car. Thats the plan anyway, but a long long way off.
