Looking at conv vs T top model . Does the rare T top model have more value in long run?

 

Probably not but they do have rarity value as only about £5000 were produced and not that many survive.
The Cabbies are possibly a bit more practical than the convertible for year round driving, especially if you can get hold of one of the (very rare) hardtops to put on in the winter.
As in all these things condition is paramount so a well sorted Cabbie will be worth more than a tatty convertible.

 

The t top has 49000. In need of motor work , interior not bad, no rust.

 

V12 or 3.6? Manual or auto?
What's wrong with the engine?

 

Auto / v12. Not getting a straight answer. Intakes, valve covers off . Sitting out side about 6 months

 

Chances are good they overheated the motor and blew the headgaskets. Once the got the valve covers off the realized they needed a headpuller ($300) plus the gasket set and decided it was more money and work than they wanted to tackle.

If you really want the car it's worth whatever you're willing to pay for it, but on the market an XJS with bad motor and interior is worth less than $1000 around this area.
