Ask to read the ACTUAL warranty docs. If they even have a copy. The pretty brochure does not tell the whole story. Unless it is a TRUE GM warranty you will find that you:
1 Have to jump through hoops to get a repair covered
2 According to most of the warranties I have read they say you must maintain the vehicle according to the manufacturers maintenance plan. AND have proof of all of it. How many of us actually do the 30K, and 60K dealer recommended service?
3. The sales guy says bumper to bumper, but it will not cover belts, hoses, tires, brakes, bulbs, etc. basically anything that they determine is a wear item. Different vehicles have different wear items, suspension is one I bet they will not cover.
4. They will disallow any repair that could have been caused by you not performing the Manufactures recommended service. The example I asked about was a timing belt issue on a sports car. I was told if it was not changed at or before the recommended interval and it snapped, no free repair.
See how this works, they look back until they find something you missed and then loophole out of paying.
So I would pass. Put the 1800.00 in 3 yr savings bonds and you will have plenty for year 4 and 5 should something go wrong. If you maintain it you should not need to use the rainy day money.
