Congrats! I've never seen "Maritime Blue". It's not "Lago Blue?"
I hope the "nearly new" tires they install are as suitable for your 
use(s) as the ones they're removing.

Does the car have UFO brakes? I wouldn't be overly concerned if it 
does have UFOs, but whatever the brakes--the main concern at this 
point should be that the rotors are not worn below useful limits. 
Warped rotors can often be "unwarped" by proper heating/cooling 
cycles but if the rotors are well under their "limit" I'd consider 
that the dealer's responsibility. If the rotors are conventional 
(non-UFO) then the cost for replacement is not great, but as you 
already know, the UFO costs are considerable if replacement is needed.

where is the boost gauge?

Look at the in-dash computer LCD display (black/gray) in the center 
of the main instrument cluster. Is it reading _anything_? If it's not 
giving *any* meaningful output, have your dealer fix it--usually 
requires instrument panel removal and cleaning of electrical 
contacts. Anyway, the computer's readout  can be cycled through its 
different functions (elapsed time, MPG, average speed, gallons used, 
miles till empty, and... boost) by pressing a rocker switch located 
at the end of the windshield wiper stalk. One of those positions will 
show boost and give a reading in "bar" ranging anywhere from about 
0.3 (coasting) up to 1.7 or 1.8 bar at wide-open throttle. With 
engine off.key ON it should read 1.0 bar. To check maximum boost 
level, accelerate with WOT in 4th gear from 2000 to over 3000 rpm; 
the max boost value should occur by 3000 rpm. A max boost value as 
low as 1.3 or 1.4 bar indicates possible problems  as minor as a 
loose hose-clamp or a bad vacuum hose (few dollars) but also could be 
"wastegate frequency valve" or the throttle-overrun bypass valve. The 
latter two are easy repairs but DIY costs will range from about $40 
to $80 for parts. Could be several other causes for low boost. But 
those are the easiest ones, IMHO. Low boost usually can be corrected 
without too much $$$, but it should certainly be a bargaining point 
with the dealer. Best to have them fix it, or at least knock off a 
hundred or two for pain and suffering.

Good luck.
