jose, perfectly fine to vent. We have ALL been there in some form or another. It does suck that this has happened and I hope things work out for you in the end.
I too bought my 67 LeMans off Ebay this past Jan. However, I watched the ad for all 7 days, then on the last day, which was a Sunday I called and spoke with the owner. I made it VERY clear that I was interested in the car BUT I told him I would NOT use the "buy it now" for ANY car that I had not seen first hand. After 2 1/2 hours on the phone and the auction about to end, I made him an offer that was $2500 less than his "buy it now" price and was $3000 more than his highest bid at that time.
After TONS of promises and gurantees on both ends he accepted my offer and immediately pulled the ad with only 2 hours left. The guy was wanting 17.5k and I went 15k but this was all based on the fact that the car would be exactly as he stated.
Once we arrived the next day after a 9 hour drive and my friend and I looked the car over and spoke to the owner (it was 28 degrees that day and we were froze) we reached in and started the car. We let it idle for 5 mins and we just knew this guy had told us everything he could and we felt confident with the purchase.
Even though my car was a very low milage, well documented car and the person selling it posted TONS of pics in his ad there was one detail he failed to mention. Upon our in person inspection we found SEVERAL dings in the car that the seller never mentioned. Not a deal breaker, BUT, I felt as though he could have mentioned it in his ad or when we spoke. I did however let him know that I felt he should have told me. He did appoligized and did seem sincere etc. My point is, you could NOT see them in ANY of the pics he posted, yet there were a bunch of them.
Ultimately I still bought the car and luckily all the dings were removed via a paintless dent guy but I was a bit ticked at the guy for failing to mention it to me. This may sound like a minor issue but you would have had to seen them and how many there were, enough that it could have been a deal breaker if everything else on the car had not been up to par.
I guess my advise to anyone looking at a car either locally or especially on the internet would be a few things:
1) Go look at the car in person, if you can't, don't buy the car. 2) Take someone else with you, perferably someone who knows more about cars than yourself (no matter how much you know). 3) Ask the owner a ton of questions with someone else with you (to listen for inconsistancies etc.). 4) If on the internet, if the person selling the car doesn't post a TON of pics from EVERY angle and or says he doesn't have a camera etc. RUN AWAY FROM YOUR COMPUTER, REBOOT AND FORGET IT! In this day and age if the person can't take or have someone else do it for them and post them/send them to you then assume they are full of crap and bail! 5) Drive the vehicle for an hour if need be. Check ALL fluids before and after the drive. Also, tell the owner you want to drive the car around for a while before you go and look at it and see what his/her reaction is. If they immediately tell you no or it's "not on the road" then BEWARE! 6) Always assume the worst. Tell yourself the engine will need to be gone through and factor that into your decision and more importantly, your budget. 7) When looking at a classic have a REALISTIC budget. IMO if someone is looking at a classic car and they want to restore it or just drive it, you need to have a budget and you need to have the resources available up front to make ALL the improvements, upgrades etc. upon purchasing the car. Here is my reason. If you have 5k to spend on a car, well you are going to need an additional 5-10k in hand to make repairs/upgrades to get the car road worthy. And if you buy a car for $7500 and you THINK it's going to take another 4k, you better plan on 8k. And again, IMO, if you don't have the additional funds up front and can only buy the car itself, be prepared to sell the car in the very near future because you will not be happy with a car and no funds to do anything with it. Also, if you do buy a classic that you are "going to restore someday" and you dive into the project without having the resources in hand, be prepared to loose money, because once you realize you are in over your head you will end up selling the car for whatever you can get just to get out from under it.
Other people may have some additional suggestions to add. These are simply my opinion based on almost 20 years in this hobby and several cars down the road...
