Six used Porsches still have market benchmarks below $30,000. Each price below is a CLASSIC.COM Market Benchmark (CMB) from classic.com. It is a figure for a typical car in that group, not a quote for any single car, and classic.com says neither the CMB nor an average should be used as the exact value of a specific vehicle. Budget for a specialist inspection and for maintenance on top.
The list at a glance
| Car | Years | classic.com benchmark (Oct 2026) |
|---|---|---|
| Porsche 924S | 1987 to 1988 | $11,435 |
| Boxster 986, base, manual | 1997 to 2004 | $13,397 |
| Boxster 987.1, base, manual | 2005 to 2008 | $20,321 |
| 911 Carrera 996.2 coupe, automatic | 2002 to 2004 | $21,966 |
| Cayman 987.1, base, manual | 2006 to 2008 | $24,171 |
| 911 Carrera 996.1 cabriolet, manual | 1998 to 2001 | $26,104 |
1. Porsche 924S (1987 to 1988)
What it costs: classic.com lists a CMB of $11,435 for the 924S, based on 15 sales over the past year. Sales in that window ran from $5,200 to $18,207.
Why consider it: It is a front-engine Porsche with the transaxle at the rear, and Hagerty UK calls the 924S the best all-round 924. The 2.5-liter engine is a detuned version of the one used in the 944.
What to check: Hagerty UK says the 924S cam and balance belts need changing every four years along with the water pump, and that the belt job needs specialist tools. It also says to check for power steering leaks and drips from the fuel tank. Ask for belt service records.

2. Porsche Boxster 986, base manual (1997 to 2004)
classic.com lists a CMB of $13,397 for the base manual 986, with 44 cars for sale when we checked. It is the cheapest mid-engine Porsche on this list.
What to check: The IMS bearing. FCP Euro lists 1997 to 2008 Boxsters among the cars its IMS kits fit, and says IMS bearing failure can cause catastrophic engine damage. It also says early cars (1999 to 2001) used a double-row bearing and 2002 to 2005 cars a single-row one, so ask what the car has and what work is documented. PcarWise also describes a small crack in the coolant reservoir as a common 986 problem, often starting with a faint coolant smell and slow fluid loss.

3. Porsche Boxster 987.1, base manual (2005 to 2008)
classic.com lists a CMB of $20,321 for the base manual 987.1, based on 41 sales over the past year. classic.com notes it kept hydraulic steering.
What to check: FCP Euro says the IMS bearing changed during the M96 and M97 era and lists an oversized non-replaceable bearing for 2006 to 2008, so confirm what your car has by build date. Stuttcars lists water pump failures and coolant expansion tank failures on the closely related 987 Cayman, so ask for cooling system records on the Boxster as well.

4. Porsche 911 Carrera 996.2 coupe, automatic (2002 to 2004)
classic.com lists a CMB of $21,966 for the 996.2 Carrera coupe with the five-speed Tiptronic automatic, based on 9 sales over the past year. The manual coupe carries a CMB of $33,096, which is above this list's cap. That gap is the reason the automatic is here.
What to check: The IMS bearing history. FCP Euro lists 1995 to 2008 911s among the cars its IMS kits fit, and names metal particles in the engine oil as one warning sign. Ask for oil filter inspection records and for any IMS work done on the car.

5. Porsche Cayman 987.1, base manual (2006 to 2008)
classic.com lists a CMB of $24,171 for the base manual 987.1 Cayman, based on 30 sales over the past year. Stuttcars says the base Cayman came with a 2.7-liter flat-six making 245 hp and arrived for the 2007 model year in the US.
What to check: Stuttcars lists coolant expansion tank failures from brittle plastic, cracking ignition coils on early M97 engines, and water pump failures as recurring issues. Ask which of those have been replaced.

6. Porsche 911 Carrera 996.1 cabriolet, manual (1998 to 2001)
classic.com lists a CMB of $26,104 for the manual 996.1 Carrera cabriolet, based on 94 sales over the past year. It is the most expensive car here, and the only one that gets you a three-pedal 911 with a folding roof under $30,000.
What to check: FCP Euro says early M96 cars (1999 to 2001) used a double-row IMS bearing, and lists metal particles in the oil as a failure warning. Ask for the bearing status and any documented work. Run the roof through a full open and close cycle before you buy.

How we picked
We started from classic.com market benchmarks checked in October 2026 and kept cars whose benchmark is under $30,000. We chose cars with documented inspection risks from published buyer's guides, so you know what to ask about. A benchmark describes a typical market price, not the condition of a particular car. If you can stretch the budget, see our 997.1 Carrera buyer's guide.
