mercedes guy,
I opted for the Euros only after reading great feedback about them in this forum ! the info I gave you was from this forum as well. They're well worth the 200 investment. 200% improvement in light if not more. as for the process, the only time u're looking forward to is removing the three bolts that holds the headlight assembly together on both sides, and swapping the connectors. Not more than an hour if you take your sweet time and do your research here on the DEPO Euro. Ashman and others have some great indepth material on it.
best of luck.
