I agree with 'Laird Scooby' and 'Stephen Edwin', 'whittonwanderer'. Both offer sound advice. Sentiment aside, corrosion, or the lack of it, is key to the decision. Unlike more modern cars, a bodily sound 7 series can often be mechanically repaired, both effectively and (usually) quite economically. Although, as has been said, values are at last nudging upwards, the cars are still so reasonable to buy that you would be unlikely to recover the cost of any significant repairs.
