Ion 3 here with sun and sound package and travel package. No leather and no anti-lock brakes. 2,500 miles bought in November. Just today had my 1st problem, key stuck in ignition - called dealer and they told me to make sure the shifter (automatic stick) was pushed forward firmly, I did that and the key did release.
Aside from that, I like the car a lot in spite of what I consider to be undersized side view mirrors and large gaps in the panels, doors etc. If it rains or after a car wash, there is a large amount of water pooling at bottom of step in door runner (lower painted part). I've been wiping it out as I don't want water sitting anywhere for any length of time and I plan on keeping that painted surface well waxed; I'll have to see how this plays out over time.
Stock all season (good for no season) tires I've swapped out for the winter with Nokian WR stud-less snows; I'll put the hard all seasons on for the summer months.
Let's see what else, sure it a fair amount of car for the money; I paid $17,000 and if its anything like the SL2 I traded in, I'll be happy. No real maintenance except oil changes before 100,000 miles.
Time will tell though...
