We have a 7yo (13 plate) Zafira - the one that spontaneously combusts, but that bit has been fixed.
Went to get it MOTd today and to get it to pass it needs:
new brake discs and pads and new brake fluid- £400
new exhaust - £460
And a handful of maintenance type things - £150
BUT in addition to this it will also need, in the next 3 or so months.
aircon condenser unit - £500
timing belt - £580
Total cost of repairs is £2200.
We buy any car would give us roughly £800, we might get £1000 if we sold it privately, but that would obviously take more time.
We don't currently have the cash available for the repairs, so it would have to go on a credit card - we are therefore limited by what garages we can use. We'd be able to pay off the credit card in a month or 2 as our household income is about to go up about £15k pa as I've just got a new job and DH is due a reasonable pay rise (currently in negotiations).
The car has done almost 100k miles as it is.
WWYD - repair or replace? Replace would likely be a car around £3.5 - 5k.
