I mean no disrespect, but why are you considering a 150 for 37k when in your original post you said your budget was mid twenties or less ? That's $12,000 over your maximum dollar. Don't make the same mistake I see people make nearly every day. They have a maximum budget and spend right up to it for the purchase of aircraft. There are two types of things that I will guarantee you will come up after your purchase. #1 is things you will HAVE to purchase. Maybe an airworthiness related part that was missed or maybe something breaks. #2 is things you DESIRE to have. Maybe the paint is some awful color or the windshield is a little too milky for you. When these things come up (and did I mention they WILL come up) you'll have no money left to fix them.
So, with that in mind, I'll give you the same advice I give people who call me. Don't spend your maximum dollar on the purchase of the aircraft. If your maximum dollar is 25k, then look for aircraft in the 20k price range and work from there. I can remember 150s I bought in 1977 that were only 2 years old and they still required at least 2,000 "1977 dollars" to put them to airworthy standards and presentable condition.
My 2 cents.
