Wow! thanks all for your advice. I never thought it would generate this much attention - especially as a late night post not fully thought through....
In detail, my mig has 118k miles on it, and runs very well. It needs the following work:
* wishbones and steering idler (asap, handling is atrocious)
* cambelt, aux belt, water pump (in 3k miles)
* cam cover gaskets and breather clean (same time as the cambelt)
* oil and filter change (same time as cambelt)
* gearbox oil topup and filter change
Minor bits - glovebox handle, sunroof surround, rear blind, decent tyres (budgets on it at the moment), nearside mirror electric adjustment re-wiring, drivers door 'cracking' fix, handbrake adjustment, nearside dispack (not faulty at the moment, but signs of light cracking and it could go), rad flush (engine temp is a bit high), and at some point the minor oil leak from somewhere underneath needs attention.
In addition, it has an advisory from it's last MOT (may 2010) that the front offside shock is weeping, so a pair of front shocks will be needed, the back end is wallowing a bit more than usual, so I feel that the donut bushes will probably need replacing soon.
I take the point that it's better the devil I know - granted that any other car I get could well end up costing me a ton of cash, and I can do all the work listed above myself, thus saving a load of money, but I am going to be in real trouble financially soon. In a nutshell, I was an IT consultant for the Building Schools for the Future programme, which has been axed wholesale by the government, so my skills are largely useless elsewhere. Jobs are very thin on the ground in my skill set area at the moment, what with about 5000 other people with exactly my skills all in the market at the same time.
I got a redundancy payoff, but the money will last me about another 3 months and then I need a job. I'll get something, but it is likely to be radically less than I was earning - in the region of a 75% pay cut, which is going to be a horrible shock.
The car currently manages about 250 miles to a full tank - all my mileage is local at the moment. 250 miles for £70-£75 is pretty poor, and it's an expense that is starting to bite. To add insult to injury, a combination of stupidity on my part and sheer bad luck has left me with six points on my licence and a recent prang (to this car - fixed on insurance), which has resulted in zero no claims, so my insurance is £120 a month - this car is group 17! I'm 40! I never thought I'd pay this much in insurance!
So, I hope you understand that my desire to save money is also based on getting something that is cheaper to insure and manages slightly more to a full tank than 250 miles - those two savings in combination could make a big difference to my financial situation.
The other trade off i have, of course, is the sheer amount of work required to make it suitable for private sale - doing wishbones, steering idler, cambelt, cam cover gaskets, water pump will still be in the region of £300 even if I do it myself, and that's an investment that I definitely won't get back if I try to sell it privately, though I'm open to your opinions on that.
The vectra idea was simply because I saw one in a local dealer that didn't *look* too baggy, and I reckon I could have done a straight swap - but in retrospect that looks like a bad idea.
I have been offered, in a months time, a 2000 plate Honda accord 2 litre from a friend for about £750 - and if it's cheaper to insure and run, day to day, then it might be worth it.
In summary, though, I must say the idea of getting rid of the mig is actually quite painful - I've had it for two years, and i'm quite attached to it now, I suppose doing a lot of your own work on a car kind of bonds you closer to it!
Any way, any feedback is appreciated. If I do decide to sell it privately, I'll list it here first to at least offer the car a good home.
Thanks
John.
