I have no problem being obvious as hell about checking a car over. If the seller has a problem, they just told me right there they are hiding something. I'm not talking about being a dickhesd to a nice car, but something like this one, in three shades of grey. But I'll look everywhere and ask questions, often leading, if I see some bad spot(s). Funny how they will tell you all that's wrong if you ask the question the right way.
On a side note, I'll have $6500 into my 500 when it's on the road, but I knew it would need the $3000 put into it, rust free saved me a lot of money. Knowing the car you are looking at helps lower the price, by knowing what to look for, and being able to explain to the seller how you came to that conclusion. Doesn't always work, but easily can. Got a car for 55% of asking price by explaining the latest selling prices and limited market for the car, very politely, and also the fact it was going to a loving, caring home.
