NICE CADDY ! Especially for $ 400 bucks ???? The " alleged" blow-by will show up in the intake hoses / valve body/ air filter/ intake manifold. Make sure they are oil free. As for the hood paint, I would just send it out to a body shop an have it re-shot ( unless you're really good at painting and have all the equipment). That shouldn't be expensive. They'll take the hood off the car and shoot it on benches. Less labor involved... The rest of the paint looks GREAT ! Lucky score !! Do what you want with the tires. I would do what Kira says, since there is really nothing more to do on the car ( visual inspection on my end ). Service the tranny. May take a few spills & fills to get fluid clean...,,and coolant change. I think changing the rims is a bit much, leave them alone....( unless you have money to burn on this Caddy) I mean, it does have 184k on the ODO. Don't go nutzo sinkin $$$$ into it............BEST OF LUCK !!!!!! CONGRATS !!!!
