If you're looking to sell the car, it's good practice to swap your old logbook for a new one. To do this, send it to the DVLA, Swansea SA99 1BA with a covering letter - it's a good idea to make a copy of the documents before posting the originals and if you're worried about them getting lost you can always send them to be signed for. Alternatively, call 0300 790 6802 - you will need to have the registration number, make and model of the vehicle and the document reference number. If it's been stood since 1992, and get it running make sure you turn the engine over by hand first - remove the spark plugs to make this easier. You'll also want to drain all the old fuel out. As well as getting it valued, you really need to make a decent assessment of what it'll take to get it back on the road. Make a list of all the parts you'll need and their prices. Budget for the worst and hope for the best - it could easily be the case that the parts required quickly add up to the price of the car. If you can do the majority of the work yourself, you'll at least be able to keep labour costs down.
