Welcome! We are original owners of an '05 LTD Roadster, Aero Blue w/ 2 tone slate gray int. N/A w/ 87k miles, was daily driver for 11 years, now garage queen. Have done 95% of maintenance/minor repair as an old school DIYer. We have no plans to ever part with this car. Few common issues have been fixed; Leaky trans. connector, "sticky" ignition switch, power seat relay, crankshaft position sensor & relay control module. While these can be annoying, with help from folks here, none of that need be overly expensive. For some, an independent, MB experienced shop w/ an honest reputation may come in handy. (We are in Hemet, west side of mountain from Palm Springs)
We, like most, had top replaced due to detached rear window, (from "GAHH" & w/labor; not cheap) But definitely worth it. N/A's are fairly comfy yet sporty & good on gas, if you don't wear heavy shoes!
One owner, mileage under say 60 to 80k, w/maintenance records would be a good find. Well maintained, I think these cars are known to go 300k miles w/o major issues.
Use Caution with known water intrusion in trunk "wells" under luggage area and/or "Skreem" module issue; can affect locking & security systems. Have not had these but can run into some $ repair.
