Addison Lee is now moving out of Galaxy diesels and into hybrids. But if you want a black used Galaxy it will almost inevitably have once belonged to Addison Lee because they ran 4000 of them, selling the cars at 100k - 120k miles. Engines should be okay because they changed the oil every 5000 miles to increase the lived of the DPFs. Powershift transmissions have sometimes needed some work, but I've been in ex Addison Lee Galaxys with 160k miles on them where the driver has only had to spend £500 fixing the Powershift.
