considering a set of miro m6 reps - help?

[r4gs]

was scouring the local craigslist and found a set of miro m6 reps listed for sale in san antonio for $750. details:

1. 19x8.5 et35 fronts, 19x9.5 et33 rears, all 4 sides hubcentric to the m coupe at 72.56mm and finished in classic m6 style silver.
2. 235/35/19 nexen n3000s brand new on the fronts, 265/30/19 general exclaim uhps 20,000 miles on the rears.
3. curb rash readily repairable on the front right.

these came off an 07 e90 328i with 29,000 miles and the set of rims were mounted in nov '08 at about 9,000 miles. the originals came with general exclaim uhps all round from **********s, but the seller had a flat from a pothole in january, thus switching out both fronts for brand new nexen n3000s (probably from the dealership).

my concerns here are:

1. possible cracks, bends to the rim that struck the pothole? seller is a salesman at bmw of san antonio's dealership and says the rims have no cracks/bends and run true. my plan is to have him show me all four wheels on the wheel balancing machine at the dealership.
2. rear offset is et33, and i intend to go with 275/30/19s. i'm concerned about rubbing on the inside tire sidewall against the struts.
3. anyone running nexen n3000s at all? they're a very affordable, decent quality tire but i'm not sure whether to negotiate to pick up just the rims and go with hankook v12s or conti extreme dw's all around (245/35/19 and 275/30/19), or buy the set as is and swap just the rears with matching nexen n3000s or something else. i do not track regularly save for the occasional hpde (will be attending one in march).
4. price of $750 for a 20,000 mile set of miro m6 reps isn't particularly good either. thinking it'll be fair at $600 inclusive of the tires, or $400 for just the rims. thoughts?

also, here's a pic of a fellow zposter's interlagos m coupe with m6 reps (unsure if they're 18s or 19s). yay/nay

As one of the hottest wheels in the BMW community today, these M6 wheels look great on just about any car. The beautiful five spoke design provides an elegant, yet aggressive look, just as they were originally intended to be for BMW's V10 M6. The nature of the wheel also allows them to appear larger than they actually are which gives your car a meaner stance. Why buy used when you can get a brand new set of wheels for a little more? You'll have the peace of mind of knowing that the wheels weren't abused and of course are brand new without any curb rash. The setup listed above is actually incorrect for the Z4M Coupe as well. The setup that you would need is the 19x8.5 ET35 with a 235/35/19 in the front and the 19x9.5 ET22 with a 275/30/19 in the rear. I'll go ahead and shoot you over a PM with more details!

^thanks, have decided against them. the set was as described but seller had misinformed me about nexen front tires. instead, they're not even z-rated tires and are from some non-descript manufacturer i don't remember the name of. rims themselves were in poor physical condition with a lot of delamination and peeling around the edges and bmw roundel area. the front right rim that had a pothole encounter was bent noticeably and had extensive curb rash. not impressed with the quality of reps, but i do understand the universal 'u pay for what u get'.

going to be sticking with the oem 224's since i've just applied a layer of klasse aio on them
