Thanks for any and all input - I've appreciated all the technical knowledge I've been able to pick up here.

I'm looking to get my first classic merc. My preference would be a diesel, and ideally a wagon.

I love the look of the S123 and W123, and also the W210 and S210 (W124 also an option). I'd do a turbo OM617 or ideally a non-turbo OM606 for later tuning. However, given the current state of inventory country wide and crazy prices (I'd love to not have to buy right now, but I need a car,) what else would y'all recommend as a simple, reliable, comfortable merc which can have a class one or better hitch fitted in the US for light towing duties (uhaul 5'x8' or similar)?

I'm fairly handy and can install a hitch myself as well as splicing in the wiring, but don't currently have access to a welder to make more serious mods in order to macgyver a towing solution. I plan to replace all fluids but want something which doesn't automatically require a dealer as soon as something goes wrong.

I know nothing about the gas options - I don't need performance, just something that can sensibly cope with the trailer, and doesn't guzzle fuel.

What should I also consider? Thanks!

If you're in the USA, you're not going to find a diesel W210 wagon. That said, the M112 engines are supposedly very well built and will go well beyond the body.
Watch out for rust in the W210, body, fenders, wheel wells, anywhere water can pool. Check the rear subframe and suspension components over very well because they can rust to the point of needing replacement. This is the case for my 1999 E320 wagon, the entire rear suspension needs to be replaced.
I love the W210 for its looks and the fact that it is a great blend of user-serviceable mechanicals plus modern comfort and safety. But if you have too much rust, it's simply not safe. Inspect your potential car with a fine tooth comb.

If your primary duty for the vehicle will be towing, find a Ford pickup with an inline 6cyl 300CI engine and tow to your hearts content. If your primary use will be as a commuter/utility car with infrequent towing, a Benz wagon may be your ticket.

Thanks Phil. It's going to be a DD with occasional towing - once every few months.

I have a line on a diesel E series sedan in the southwest with no rust, so that part should be no problem. I hope to pick it up this weekend and drive it back across the country. I'm getting an inspection done, but finding someone to do it in the available timeframe is proving difficult.

Thanks for all the pointers!
