Invest In This '08?

I bought mine in '10, certified with 32K miles. I'm now up to 185K.

Having spent 13 years with this SUV, I've grown fond of it's shape, size, handling and performance. It's never given me any outlandish maintenance bills, but last year it started losing oil (burning, not dripping) so now I add a quart about every 5-6 weeks.

Would it be wise/feasible to invest about $3K, including tires, to keep this baby in good running shape for another 18-24 months?

And, if so, what are the areas to focus and spend the most on? Assuming the engin can keep going with the periodic oil addition, I'm thinking transmission, front end, exhaust.

Ideas and recommendations appreciated.
