Replacing E30 M3

[mags]

I am thinking of replacing my E30 M3, I still love it, but its showing its age, and the lack of power below 4k rpm annoys me. I would like a Cerby, but I realise I need to spend about 30K to get a dealer one with warranty, I can do this, but reliabilty problems are making me weary, what else is worth considering? My M3 has been less than reliable, I have probably spent Cerbera money servicing it in the past 3 years. I dont want a soft top, I have an Austin-Healey Sprite in the garage, and I dont want a TT/Scooby/Evo, or anything FWD. Help me please!
