Wondering when it's time for your next service? As a general guide, we recommend oil changes every 7,500 to 10,000 miles, a brake inspection at least once a year, and a full vehicle inspection during every service visit. Since every vehicle and driving style is different, our Brooklyn team is happy to help you build a maintenance schedule that fits your needs. Schedule your visit.

18 year old Porsche Cayenne. Under 90,000 miles.
Customer calls us frustrated.

Told he needs an alternator.
Shop can't get one.
Dealer says a month and a half — coming from Europe.

We said bring it in first.
Let's make sure that's actually what it needs.
Because we don't just take someone's word for it.
We verify. Every time.

And this isn't just any alternator.
This is a water cooled alternator.
Look inside — you can see the carbon buildup
from the windings coming apart.

That's a Porsche specific part
that most shops don't even know exists
let alone know how to source.

We sourced it in four days.
Not a month and a half. Four days.

Replaced. Fixed. Done.
And he'll have his Porsche back
for a weekend away with his family.

This is what being the European owner's answer
actually means in real life.

A Maybach walked into our shop today.

And the owner didn't come from around the corner.
He came from the city.
Because nobody else would take it
except the dealer — who told him weeks.

Weeks.

For someone who owns a Maybach
that's not just inconvenient.
That's unacceptable.

He found us. He made the trip.
And we took care of him the same day
we take care of every customer that walks through our doors.

With the right tools. The right knowledge.
And the respect that car deserves.

Maybach owners —
you have an option in Brooklyn.
You don't have to wait weeks at a dealership.
You don't have to feel like nobody wants to touch your car.

We do. And we know how.

BMW heat control module replacement.
45 minutes just to disconnect the hybrid battery safely.
Then intake manifold off. Six more assemblies removed.
Just to reach the part.
This is why the labor costs what it costs.

Vacation tomorrow. AC died last night.
Found us online. Never been here before.
Brought in his BMW M750i this morning.
We're getting him on the road cool. Because that's what we do.
