The future of the threatened Jaguar plant at Browns Lane in Coventry will be discussed at a meeting in the House of Commons on Thursday.
Staff could be leaving Browns Lane for other sites
There is speculation the luxury car-maker is looking to close down its operation, and move the remaining wood veneer workers to another city site.
Coventry North West MP Geoffrey Robinson has organised the talks.
He said he understood a firm was interested in buying the plant, which is also its headquarters.
Four UK sites
Parent company Ford has drawn up ideas to move staff to other sites, such as Whitley in the south of the city.
It has 2,000 employees in Whitley, plus 3,000 in Castle Bromwich, Birmingham, and another 3,000 in Halewood, Merseyside.
Car production ended at Browns Lane, Allesley, on the edge of Coventry in July.
About 500 people are still employed at the site which is mainly used for wood veneering. Jaguar has been at Browns Lane for 53 years.
'How many jobs?'
Geoffrey Robinson arranged the meeting with new Jaguar/Land Rover chairman Geoff Polites, trade union officials and local MPs to discuss the future of the Browns Lane site.
He said: "I'm after assurances as to what will happen to the administrative HQ and its office staff.
"I'm eager to know what the plans are for the site, if we do have another manufacturing company poised to take over the site then how many jobs do they plan to bring with them.
"We need to know how far the discussions have developed with this possible buyer and how much they are willing to invest in the site long-term."
