i've had a 300CD for a few years now, single-tank conversion to wvo/biodiesel/diesel, 360k miles:
everything pretty much works - it should, as this is the stuff i've replaced over the past few years:
power steering pump
power steering oil pump
fuel lines, etc., to make it biodiesel safe
valves and a couple major tune ups
bushings and steering bits 2x
replaced fuel tank (w 18+ gallon)
oil pan recently
and other stuff adding up to around $8K in repairs over the past few years.
the good: it's in really good shape - intact interior, uncracked dash, clean, a few minor dings here and there, but no rust and well maintained for a car of this year and mileage. it also performs really well as long as i tune it up every so often or drive it daily.
the bad - getting kind of tired, it is running at 360+ miles, the front end stuff tends to need refresh every year or two (could use it now) and it leaks a bit of oil when stopped, has a slow radiator leak, a few minor bits (OD stopped, cigar lighter out, few vacuum leaks, AC needs recharging, rear window motors are a bit tired, some particulate in the exhaust at night.. turbo lag is occasionally annoying, needs front shocks, tires, etc. (also not as clean as the picture above, which was about 5K miles ago, but that should mostly wash off)
so my conundrum.. i'd love to stay in the 123 world, but would like to get two things out of it:
1) a stick shift, 5 speeds ideal
2) fewer maintenance issues than the CD i've got
so i'm thinking i should either:
A) sell this CD and pick up something else, adding 2-5K cash and whatever I get for the car to my new-mbz fund, and looking for a W123, like:
- 240D with a 300D turbo swapped in
- 300D euro version with 5-speed
- 240 D with an aftermarket 5 speed,
B) spend 2-5K on the CD - like transplant a 5-speed into it, a new ODO panel, an engine rebuild, new wheels, etc.
any opinions? which path will cause me less pain, do you think?
