Here are some ups and downs to the truck... personally i wouldnt buy another one.
I own a 2005 chev colorado, great truck...but ... there are soo many electrical problems.
problems i have been having:
air in gas tank
heater wont work(brand new blower motor, still no go)
signals will work sometimes and sometimes not.
The truck is always telling me a have a door open when infact they are all shut, which brings the interior light on when i stop at red rights(very annoying in low light conditions)
The cig lighter outlets will work sometimes and sometimes not.
Now for mecahical (my rating 8/10 for this truck, very good truck mecanically)
brakes, front and back last aug, fronts need to be done now as expected
left axle
I have driven this truck to Newfoundland 4 times with this truck
hope this helps. goodluck
