Nice customer service and maintenance job but had few challenges :
* their car wash service was broken so no washing.. They said should be fixed in 4weeks but visoted after 6weeks and still broken!
* car's audio system has probably loose wires as sometimes right side woofer stops playing and but they had no idea and asked to replace the woofers or visit audio specialist!
* couldn't upgrade my navigation map claiming it was installed by some 3rd party vendor and something is wrong but you are supposed to fix, whatever is wrong, aren't you?!
