1990 325i vs 92-94accord help me out here

Alright I'm looking to buy another car (the RL will still be around, no worries) but i want someone small, light and faster then the RL. I also want something sportier, and something i can tweak.

A friend of mine john is a bmw fan and is in the process of talking a a 325i and restoring it. He currently owns a 325ci convertable that hes bored out to a 3.0l engine and that thing flys.

The one he would be selling me is a 1990 325i blue, with crossed drilled rotors, spolier (bmw's) and side kit. He says he'd be willing to sell it to me for $6500 CAD or $4000 USD it currently has 140,000km or 87,500miles on her. I've started up the car and even though its been sitting for the last year (before he bought it) it just jumped to life and sounded great. There has to be some work done to it and he would be doing all that before i get it. Its currently in his cousins body shop getting a dent fixed. Not to mention he has all the service records as hes the 2nd owner.

now the question is do i stick with Honda and try to get something sporty from them or do i get the BMW? I've been doing my research and these things stick to the road .85g and 0-60mph in 7.7 and 1/4mile in 15.5s i think. So right of the bat i like the sounds of it, not to mention i might bore it out to a 3.0L which would bring the times down into the 6's.

Also if i go with the BMW people are warning me about the cost of maintaining them. I have heard that dealerships charge alot for regular service but i've heard that with the right tools they are easier to work on then hondas.

so lets here it people.
