Hey Carroll,
Have you asked your employer what your options are? It is probably just a cost cutting move since the lease is now over. If you are posting this from in the US, then this is not necessarily considered compensation. It’s kind of like the office coffee pot or the water cooler, a convenience.
Has your employer told you what they are offering in lieu of the company car? (Mileage, insurance reimbursement, parking permits) Are you expected to visit with clients regularly? Will your current vehicle reflect poorly on the company? Depending on the answers to these questions you might be able to:
1). Lease the car back from the leasing company – you already know how the car runs and the maintenance history
2). Be able to work out an equitable reimbursement plan with your company that is not adversarial.
3). Look like the hero in all of this. Other employees that also get company cars are going to complain like hell. Rise above that fray and find out how you can be of assistance.
You have no rights because this is not considered compensation, but do yourself the favor of positioning yourself in the winning category.
Good Luck,
James in San Diego
