94 325i W/ M3 swap should i buy?

Just want to start off by saying hi, new to the site and looking to get some help so i can make a good decision. Now to my question. Ive come across a good deal or so i think. My boss is selling his 94 325i w/ a motor from a 95 M3 in it. I offered him $1500 bucks for it and he said he'd take it. The reason its so cheap is because the motor is blown or so we think. The cars been sitting for about a yr and he just wants to get rid of it. Now what happened was he missed a shift. Instead of going 3 to 4, he went 3 to 2. He was close to redline when he did this so the car definitely over revved. He said he got out of it as quickly as he could and shut the car off immediately. Then when he went to restart it, it didnt fire. The motor cranks so the engine isnt seized which is good. There also is no coolant in the oil so the headgasket isnt popped also good. So going by this whats the best/worst thing that could be wrong? How much will it cost me to fix? Is $1500 a good price. I think it is because the car isnt stock. As it sits now its lowered, has 19" Hamman wheels, Remus Exhaust, leather interior, and some other stuff. Ok well if anyone has any help or suggestions it is much appreciated.

Welcome. Most likely, there would be some valve damage. So a rebuilt cylinder head may be needed. It's possible that piston to valve contact occurred also.

Yea, I assumed theres probably some valve damage so i figured it would cost around $400 for new valves,springs, retainers etc. Where would i go about getting a rebuilt head? Cost? and what comes with it?

Repair shops usually have contact with machine shops that offer rebuilt heads.

Yea i called around for a rebuilt head and i found one for $2000, thats a lil pricey as is im only 19 and still in school. Is it possible it spun a rod bearing,blew a piston ring or are the m3 engines built pretty tough and can be over revved once and not grenade itself?

Top end damage is much more likely than bottom end damage in the situation you describe.
