Welll...... I did the exact opposite.  I got rid of my 1991 Range Rover
to get my Westy.  They are decent cars in general, but they need to be
kept in top shape or one problem will create two more.  Also the parts
are generally about 2.5-3 times more for the Rover.  If you do your own
service they are not that hard to work on but parts can be a pain.  My
overall opinion is that you should be getting a significant amount of
cash in addition to the car if you do the deal, becuase I guarantee as
the price of gas rises the value of that Rover will continue to
plummet.  I don't know what the market for Rovers is in your area but in
california where I'm at I got $4500 for my Rover, which was in showoom
condition, and it took a month to sell.  Today I'd be surprised to get
$3000 in the same scenario.  On the other hand your Westy is holding
it's value and probably going up.  So.... I guess what I'm saying is I
don't regret losing my Rover for a Westy for a second.
