Gents,
I've a 1989 Mercury Colony Park wagon I've substantially modified for long day Interstate travel. It racks up 20 k annually.

In Europe recently I drove Mercedes, Vauxhall and Alfa Romeo rental SUVs.I liked them. While my wagon has satisfactory mpg (21) and on ramp punch, it's nearing 300k and next year or so I'll need to replace the engine and tranny.

The wagon weighs 2 tons empty. Its engine compartment is relatively long, wide and shallow.

Internet research suggests that the Jeep/Mercedes 3.OL might fit but I've no idea for a tranny.

I'd be grateful for any suggestions or suggestions where I might look.

Thanks, Donald McCaig
