Thats not good James 
Had you started the lpg conversion on it yet?
No, thank god...
What are your plans James? Few Ideas....
* Fit Replacement Autobox?
* Convert to Manual?
* Break...
Tbh you have had a few cars recently.... is it worth pushing the boat out for a facelift? Plenty of 2.0 / 2.2's out there, the later 4pots are much more refined. LPG it and your away 
My plans?
They are like this
Something that has more than half and engine (Eg a V6) preferably a 3 litre, and doesn't sound like a tractor.
Something with Climate Control
There are still many sellable bits from my old V6 that could help with contributing.
Manual conversion, forget it, I want auto.
On the plus side, I now have a job that is only 9 miles from home, rather than doing 500 miles a week..... so fuel economy is not such an issue anymore... meaning I could potentially have something mega beastly.
LPG, I would love it, but I'm considering the option of possibly getting a brand new SGI kit for a V6 instead, as Martin says, get it all perfect over the summer.
I will have a think, not committing to anything yet.
Another problem is that I've had so many changes of car, my insurance are getting funny about it

And now are the later 4 pots more refined? Aren't they mechanically the same?
