My perspective will mirror other Members I am sure, but will not reflect the views of all.
I bought my GS just over 5 years ago from Lexus Chester which has completed all servicing (via a Service Agreement, costing £34 per month fixed, during that period ).I also purchased and continued to purchase an Extended Warranty which ran throughout that period and the current one still has the best part of 2 years to run.
The Dealer is 6 miles from my home and I knew of Lexus Dealerships at Liverpool (10 miles away ) and Bolton (30 miles away). Indeed Lexus Bolton offered to collect the car from my home and return it to me after servicing, stating "that`s what we do".
I bought the car for the long term (still having my 16 year old W210 Merc Estate). The principle reason for my choosing Lexus was their reliability, perceived quality and famed Customer Service,. both of which have been first class. I have had no problems whatsoever with the car (servicing and consumables only) and customer relationships have been all that I would have wished.
I did not and still do not, see the logic in investing in a Lexus, to then "spoil the ship for a halfpenneth of Tar".
Having invested as I did, it is not necessary for me to worry about Dealerships being x miles away, or expensive for servicing or repairs.
As I stated at the outset, not all will agree with my views, but I can claim to have been pleased with the outcomes of my decisions.
