Unless your getting it under $6,000 USD then Id recommend not buying it.

1) If the window regulator is bad its going to def cost you more then 400 to replace.
2) Windshield cracked, its going to cost at least 400 or more to replace, if its minor then try having it tinted....
3) Left turn signal not working at ALL? Not front or back? If so then check the fuses.
4) SES Light means a BIG no no. Id connect an ODB II and read the codes the car gives you. It can be anything from putting in the wrong gas type to ... engine going out....
5) Cluster, Dead pixels is a HUGE issue. To replace the cluster will cost you over $1000 USD at the dealer and if you go ahead and send it in to be pixel fixed to one of those MID Pixel Repair places your going to wait a long time and it might not fix all the pixels....
6) If its the OEM Year 2000 headlights then id recommend you changing them with the HALO styled headlights from ebay. There not that much, maybe around $200 USD.

Good luck with whatever you choose.
