Hi everyone just after a wee bit of advice really... We have had our pre-facelift 1998 manual MV6 for nearly 3 years now.it has covered 125,000 and never let us down once

It is in the rare "Antelope" colour and has the velour interior.
It had 1 previous owner before us who really looked after the engine he had it serviced at a main dealers in Blackpool and we sent off for a print out which gives for some good reading.
There are a few bits of rust on the bodywork too.
Anyway just recently it has felt really funny on the front end and reading the forums it seems like the wishbones now need replacing.
It has affected the front tyres which were new not that long ago

The airbag light is on all the time and we found it it was the drivers seat airbag.A lot of people have said it could be lose wires underneath the seat ?
We have just bought ourselves another manual MV6 with only 54,000 on the clock with FSH and so within the next week or so our original MV6 will be up for sale. It runs out of tax at the end of December and needs an mot in January it sailed through the last mot and the garage said it will prob need its brake pipe replacing next time.
So..this is our dilemma do we sell as is or get the wishbones replaced before we sell ?
Your input is most appreciated
