There should be no excuses about missing service history - it's free after all! Walk away from any car that doesn't have one. Best cars are still within the Daewoo dealer network with growing numbers on the private market. Depreciation makes it quite a bargain.
A steady market for this car. It's modern, well-equipped and the three-year servicing/warranty/breakdown cover which is transferable between owners. Depreciation means prices are low, too.
