Re: m5 e34 vs m3 e30 which one to buy?
I had the same hard choice several years ago. The first one to come up was an '88 M3 that needed a little TLC...so I bought it. This is definitely the collectible car and will hold it's value the best. And, it'a a blast to drive. Great on the twisties.
Next was a '91 M5 several years later. I bought it and now can compare the two side by side. For power, comfort and long distance driving, the M5 is superior. It's a heavy car, so be careful throwing it around corners. The back end will dance.
The M3 is so secure. It's like a go cart. It corners extremely well and is very predictable. But, it is a bit rougher, more vibration (the famous shift lever rattle) and peakier power.
I love both, but I get more thumbs up for the M3.
