Do your basic maintenance, repair the occasional small part failure like a VVT solenoid gasket, and the car will run well past 300,000 miles. For vcm, you want a VCM tuner II. It will protect your engine from fouled spark plugs, oil consumption, piston ring damage, and cat failure caused by oil burning and then clogging them. It's well worth the $120, and once installed it will likely last the life of the car, as it uses automotive grade parts unlike products such as the SVCM, which is known to fail within a year. I find that I get 20mpg in basic town driving, 15-17mpg in constant stop and go town driving, and 30mpg at 85mph on the highway the one time I've taken mine out so far (bought it in November, but once the temp plate expired I didn't get new ones until just 2 weeks ago). I'd be curious to know if yours has navigation and the price, as I monitor the crosstour market and the prices on them are still fairly high. Also, how do you like those Michelin Crossclimate 2 tires? They are expensive, pretty nice to come free on the crosstour. I've been wanting them as I need new tires, but are they quiet and have good handling? I haven't seen anyone else put them on a Crosstour yet, so I have to ask.
