2006 E53 6spd MT, 187,000 miles, keep or replace

[rwilson]

Last week I had all the brake lines replaced ($1,500.00) and while the
vehicle was in the shop I started my search for new SUV in the next year or so.

I purchased the 2006 as a CPO in 2/2010 and since that time my total repair costs
amount to around $11,000, starter/alternator/radiator/brake lines/etc.

Note: there does not seem to be an increase in annual repair costs over the last few years
(except the brake line costs which messes up my 1k/yr average)

Note: I do not include maintenance items in the $11,000, tires/oil changes/upgrades.

Note: X5 is not my primary vehicle and is used for ski trips/hauling stuff/etc. So maxmimum trips are about 200 miles.

I have narrowed the new SUV down to another CPO X5 or Ford Explorer ST with
an out the door costs between 55k & 60k and this assumes my current X5
is worth no more that 3k-4k.

So the question is should I purchase an new SUV or use that purchase money to keep the X5
running for another 10 years.
I really like the 6spd and really like the idea of not putting up with all of the new electronic beeping devices.

Note: I assume the new SUV would have minimal value after 10 years

Note: Due to the age of the 2006 x5 I am no longer taxed by the local government,
but the new vehicle would be taxed at about $1,000/Year

Thoughts appreciated
